[How long will the Wolf stay?]

I believe its 5 weeks left. I'm at rank 27, its been super easy so far, the index one was KIND of a challenge, but ya. You should try to get them no matter what cuz theres many good rewards, you probably wont get to rank 29 for the umbral forma, but you can still get some good rewards. 
Tbh tho, you should have already started doing this.

I'd like to extend this to future umbra's also. It's unclear if we will even get more or not but I'd like to have the options for future fashionframe.

there shouldnt be future umbras. Excalibur was the first warframe, umbra was the prototype, made out of a human. Thus no other umbras needed

I completely, and wholeheartedly, disagree with this.  I appreciate you for being a founder, given that console never had the option, but you already have a shiny "exclusive"  warframe that is statistically equal.  Asking for this is essentially asking for more exclusive treatment because you are a founder, and objectively that's not fair.  I commend that you supported the game in its infancy, again consoles never got a chance (I'm obviously salty), but you already have your exclusive prime that no one else can acquire.  Doing so, I.e  giving founders the option to use prime cosmetics on umbra, would open up the floodgates of the Excalibur prime forum wars again.  Please let sleeping dogs lay in peace.  Sorry if I came of as abrasive.
