Mission 782 Speakers problem

I’ve just got a pair of these speakers - they work (with a Yamaha RX-V375 amplifier and Denon DP-29F turntable plus an LG TV) but one has a pushed in tweeter and both mid-drivers don’t work. The damage me tweeter still works and I’ve tried taking it off to see if I can pop it back out from the back but it’s sealed up tight. Apparently the mid-drivers were notorious for failing. 1. Could I use a vacuum cleaner to suck the tweeter back the right way or would that damage it further? 2. Would something like this (https://www.ebay.co.uk/itm/313641635509?_skw=5inch+8+ohm+speaker+driver&itmmeta=01K13BSX64QDXV7AAKCHTDDABT&hash=item49067f8eb5:g:iRgAAOSwyLtmFQrf&itmprp=enc%3AAQAKAAAA4FkggFvd1GGDu0w3yXCmi1cJr6Zp1cxMM4QoGpb6JMGbjjjW50UCRGggmbMvkhl6CUtiI7uD05jHRFQFtG7BC315AIfg81lgOL1eg51fwjB1L6yo%2BOpuDAQO5kBQa%2BW3PHzsvGMFE5ZFOlklZmfLmHvrdR3oUC8dZNx0MD1jdJQgoH%2Fb24wfN2qF4RbUNcS1JlFZTqSctOVpgPLHpzXBrepfKvaOVMKn3BwQ%2FoI4IsAqqDETMolRro9VqXd4%2BOASfYnsh2WdOyKlfFVmuM9lXxoVDuyZcASan7czlE2Jy5Sj%7Ctkp%3ABk9SR_DT5-uIZg ) be a functioning replacement for the mid drivers? Thanks
