With Chaos ability you could maybe do something, but theres kinda lots of problems with Chaos, so it will be pretty hard and everything, since it requires new unittypes and chaos abilities, you cant really make it dynamic like for real.
But, Ive seen people doing abilities that incerease attack range for duration, by using Chaos. For small stuff like that it works.
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
