I want to do a proof-of-concept project (stability is not important) using some Linux features not introduced before kernel v3.14, on a TP-link WDR4300.
Having not done much OpenWRT or Linux kernel development before, how much work (if it's possible at all) would it be to upgrade the kernel to v3.14 or later?
Appreciate any answer

It depends on your skills:
As an example you can review many changesets that add new kernel versions:
There are changes specific to a hardware platform
https://dev.openwrt.org/changeset/37214 ( ar71xx: add linux 3.10 )
and several patches that increase the version number or fix breakage
and generic changes that are introduced earlier:
https://dev.openwrt.org/changeset/36657 ( kernel: generic: add 3.10-rc1 support )
afaik generic 3.14 is already available so "only" ar71xx specific patches remain
I tried to get 3.14 working on WDR4300, but had no luck getting it to work.
I have now gotten a hold of an ASUS RT-N16, which is a brcm47xx, and I see that 3.14 patches and config are located in the target folder. So i changed the Linux kerne version in the brcm47xx Makefile into 3.14.12, hoping that this was enough to make a fully working OpenWRT image with 3.14 kernel.
After make menuconfig with target set to brcm47xx (MIPS), subtarget Generic, and Target profile Broadcom SoC, Ethernet, WiFi (wl, proprietary), OpenWRT compiled. But flashing the image to the router just makes the PWR led flash/blink fast.
Should this work for the router (as the patches are available in the targetfolder) or isn't 3.14 that easy to get running?
I don't think switching from 3.10 to 3.14 caused any problems for brcm47xx. I would guess using 3.10 would result in blinking LEDs as well.
Can you attach serial console and grab the boot log for us? So we can know what causes "blinking LEDs".
I did the same test, switched kernel in Makefile to 3.14.12, compiled and installed on my device with BCM5357C0. Works fine.

Are those patches ever submitted upstream so they get merged with the mainline kernel?

I tried compiling and running 3.10 again, and you're absolutely right. The LED are blinking here as well, even though OpenWRT are working.
So I got the serial output of the 3.14 build, and here it is (does seem to stop here):

EDIT: OpenWRT seems to be running, as I can use Linux commands as ls, etc. uname -r reveals 3.14.12 kernel as well! So the problem is that it doesn't work as a router (I cannot connect to it using Ethernet) so there may be some net packages that are not working.

Huh, did you manage to compile OpenWrt without b53? Weird. What can you see in:
grep B53 build_dir/target-*/linux-*/linux-3.*/.config? You should see B53 driver enabled (=y) with B53_PHY_DRIVER=y
The output from that command is:
# CONFIG_MIKROTIK_RB532 is not set
CONFIG_B53=y
CONFIG_B53_PHY_DRIVER=y
# CONFIG_B53_MMAP_DRIVER is not set
# CONFIG_B53_SRAB_DRIVER is not set
CONFIG_B53_PHY_FIXUP=y
so the driver seems to be enabled. What made you think the driver where disabled?
You are supposed to see:

Nice! Now it works, thanks 
I have been using the 3.14.12 kernel build on brcm47xx for a couple of days now, and it has been working well. But I have now run into some problems when trying to connect a USB dongle to it. (It is a Bluetooth dongle, but before I install any BT specific modules, I just wanted to make sure it could detect it when I connect a USB device).
I have downloaded the trunk, changed the Makefile to 3.14.12, compiled using target brcm47xx (MIPS), target profile Broadcom SoC, all Ethernet, WiFi (wl, proprietary). I have also have put a (*) on kmod-usb-brcm47xx, kmod-usb-core, kmod-usb-ohci and kmod-usb2. Here is my bootlog (when it is finished booting I plug in two USB devices, and as you can see only one of them gets recognized):
