Someone will challenge the WNBA's "22" rule in court and they will win. Paige could be that person. I don't think that's her mindset, but I think it's possible she doesn't stick around for her junior year anyway. One thing she could do is just go to Europe/Russia (not Siberia) before she's WNBA-eligible, make a million bucks a year, and forget about the summer rec league (WNBA).
But I think 1) she will be loyal to Azzi, who she heavily recruited to UConn, and play with her for a year or two, and 2) she may actually need a WNBA presence to maintain/grow her lucrative USA social media stature, where her earnings could exceed her Russian basketball earnings (definitely would exceed her WNBA earnings but - ironically - might depend on her WNBA presence).
