Using Peerless from M7s for RTA12s

I just got a pair of M7s w Peerless and am hoping to possibly use them in my RTA12s whose Peerless tweeters work intermittently.
The 7s are in good but not stellar shape. I have another pair of 7s w/ the SL2500 (I think) so I can use those and part the other for my 12s if possible.
One of the Peerless of the 7s was not working when I got them. I replaced the fuse and pulled the tweeter to check for loose wire but all were tightly soldered.
Is there a way to "jump start" a nonworking Peerless? It looks fine from the outside. I notice what looks like foam behind the central hole on both tweeters. My RTA12s Peerless don't have the foam and I am wondering if this is a later design change.
Lastly, I think I've read I can't use the 7s MW in the RTA 12s b/c of ohm diff. Is that correct?
Thx!

If I am following this right, I wouldn't mix the components together. To me, this would be like wearing different shoes. Yeah it would work, but it just doesn't seem right. Each speaker is engineered differently depended on size, output, frequency, ohms etc.
If a tweeter is blown, there is a chance the woofer isn't "up to par" (functioning at its intended level).
When I blew my old Altec Lansing speaker's tweeter, I set the entire unit aside and upgraded.
