CW is not the optimal place for a "new weapon".
It would be complained about that it isn't in the non-CW queues, so I don't even want to get there.
What you really want to do is provide "Loyalty variants" through CW for each faction... the idea is kinda like those Loyalty medallions (but not a paltry bonus of 1.25% per medallion) that is "specialized" for that faction and providing bonus LP. Making them "exclusively" obtained through CW would actually be a worthwhile goal for some people (especially the Pokemech collectors).
New weapons don't solve the problem.
Note: Having reread the premise (the original post), I don't think that's "good enough" motivation (another battle of Tukayyid of sorts) to introduce the weapon given the current CW situation (massive CW burnout). It sounds "cool" on the surface, but honestly it still doesn't solve much in the grand scheme of things other than pro-Clan people saying "hey, where's our *insert preferred weapon here" and such. Then again, PGI is still notorious for leaving weapons terrible indefinitely or for prolonged periods (Flamers and MGs come to mind).
