Chances seem slim. You could always cancel your open itins. But even more, UA is famously stingly in status matching other carriers top tiers. IIRC, the process is lengthy, involving a committee review with a strong "no" bias (try a search to read others' accounts of this). This being so for people who have demonstrated already flying around 100K miles, I would say that other ways of entry are even harder.

However, late last Fall before the double EQM promo, UA comped some MP members 1K, though the criteria for doing so remained largely a matter of speculation. But of course, I wouldn't bet on being one of the lucky few.
