Thiel Owners

Hope everybody enjoyed Easter.
Just a new chapter of my Thiel 3.5 Odyssey. For those who did not read the previous thread I burned one tweeter and one midrange of my left cs3.5. Today after one month I finally checked with a new midrange (different model, borrowed) and luckily the speaker works,so the xover is safe! 
Now I need to change both or get them repaired. ( I am stubborn, I am not going on to YG, Kharma or B&W...)
On ebay I found  this guy selling a working tweeter ( https://www.ebay.com/itm/254177357767?ul_noapp=true) for 110 Euros which I do not know if it's worth it, but still it leaves out the question: how to fix the midrange? Also I noticed that this midrange was already repaired, by comparing this and the other there are clearly some traces of glue surrounding the dome.... ( I cannot enclose pics).
Any advise advise is welcome, options I am thinking are:

1. Try to repair locally (fast and cheap maybe...), with the risk to damage irremediably both....
2. Get with Rob to get his advise and a (possibly) quote. This scares me a bit since my last experience with him...
3. Wait for him and Mr. Thiel to issue the cs3.5 R with a new tweeter, midrange and X/O (gesstimate on timing and cost?).

^If you’re having doubts about going to Rob, perhaps you should consider reaching out to Miller Sound for top notch driver repair.

for what it is worth,  my interactions with Rob G were great. 

Dino - I suggest that you contact Rob. Note that if he neglected your prior request, it was not intentional. Rob has the best chance of supplying relevant information for your decision.

Regarding option 3 above: My present work is all preliminary, and I am making parallel progress on various models, measurement models and lab protocols. But a CS3.5R is hypothetical, with no meaningful timing. When it does issue, it will include some valid driver solution such as replacement drivers and/or repair potential.

Unsound & Tomthiel,
Thank you. 
Tom, glad to hear you will eventually be working on the CS3.5 R, so it leaves to me no chance but then repair my gears. 
So, If unable to fix locally, I will definetively reach out Rob for a preliminary opinion. I am pretty sure something went wrong but it was not intentional.
