Am I crazy to upgrade?

Hello all, I’m currently on the vetge of making a multi thousand dollar "upgrade" and thought it would be prudent to get some insight/ feedback from those that know before pulling any triggers. 

I currently have a 7.2 system with B&W 804s, 805s, SC1s, Htm1 & 2 Rel Storm iiis.

I have 3 Emotiva gen 2 XPA1s, an XPR5 for the rears, XMC--2, and a Blusound Node 2.

I have always wanted the Tekton Ulfberhts with two 410 subs and wide Double Impact center. I have the opportunity to pick them up at a very reasonable price as well as the Impact References for rears. So, when you upgrade your speakers you have to upgrade everything else. :) So I was thing Parasound JC1 monos and a JC3? Maybe a ysed Anthem AVM 70 or 90? Or a NAD M12 or M17? Ir Wyred 4 sound SX1000R monoblocks? Keep the Emotiva? Any input would be greatly appreciated. Thank you!
