BSSID Change Is Possible on New Firmwares?

Because recently it is not possible (so far) to change BSSID on Mango (look here BSSID change - #10 by alzhao) I would like to ask if this same problem will exist on other platforms.

If I use mv1000 or MT-1300 or 750s or 750, will the same problem exist using new (GL) firmwares? It is very important to have the ability to change MAC and BSSID like exists in OpenWRT.
