Hi Koodik,
This is possible if you'll be using 3rd party (open source) firmwares such as DD-WRT, OpenWRT, Tomato, etc. But with stock firmware, this might not be possible due to some standards (imposed by several certifying bodies like Wi-fi Alliance, FCC, etc.) applied prior to the development and release of mainstream router brands. Aside from that, these mainstream router brands are intended for SOHO market - targeting household owners that don't dwell much with advanced technical aspects.
It may not be relevant but I'm just too excited to share this: just heard a few days ago, Linksys once again released an open router - the WRT1900AC and based on it's specifications, it is intended for enthusiasts and developers alike - and it's even shipped with DD-WRT firmware out of the box! So, if you are planning to have a flexible router, you might want to check this new baby.
Hope this helps.
;)
