Lost on next upgrade from SME 20/2 + IV.Vi arm ...

I am really struggling on what upgrade to do next. I have several thoughts. Budget is 15k or tops, prefer to keep it to 10k.

1)I could upgrade my BAT 51SE to a BAT REX.
(my thoughts, a good step up, but another box with heat pouring out, another power cord, and a bunch more tubes in a already all tube system)

2)upgrade my vinyl front end. Several thoughts here..

-Keep the SME 20/2, upgrade the arm to a Graham Phantom, Triplanar, or maybe DaVinci/Shroeder.
-Keep the SME 20/2 and SME IV.Vi, upgrade to the Purist anniversary tonearm cable from my current Venustas.
-Trade my VPI 16.5 cleaner in for a Loricraft.
-Trade the SME 20/2 for a TW Acustic Raven AC, keep the SME IV.Vi arm.
-Trade the SME 20/2 for a TW Acustic Raven AC, and get a new arm.
-Trade the SME 20/2 for another table?
-If I trade the table&arm, then what arm?

My system is posted. I'll appreciate all thoughts and comments. I've read about all the posts I can on the arm and table choices I've listed above. I've also emailed a few of you on my selections above.

Also, one choice is to chill out and just enjoy what I have. It's pretty killer as it is. If I want to spend the money still, give it to charity or church.

Thanks in advance!
