Maybe RJ could step into that role.
At 5'8" and not a very good shooter I don't see her being a starting SG. But I could see her taking over the backup PG role full time and not needing to re-sign Ty Harris or finding some other veteran backup PG. That frees up 400k for other parts of the roster.
Boston 1.55MM
Billings 800,000
Lexie 803,2500
Clark 597,596
Raven 300,698
Timpson 305,250
That's $4,356,794 committed for next year assuming they don't give Clark an early raise. Dantas's contract isn't guaranteed and they have to cut her from next year's roster. Cap is likely going to be around $7.7MM next year, so that leaves $3.2MM for 6 roster spots for an average of $533k per player

Basically, they have to find a way to get Billings or Lexi off of the salary cap. And the WNBA does not allow a team to "eat" a portion of the cap hit for a player when trading them, allow cash considerations in a trade, like other leagues allow. So that means the Fever would have to sweeten the pot with a 1st round pick, which is equally bad for them because they need some of those cheap rookie contracts for the bench to help their salary cap.
If only there was an expansion draft this season.
