This seems very nice, I will try it in blitz but these positions are not so flowing for White.
I play the Haxo Gambit and sometimes I struggle to punish the dubious king even after getting one of my top lines in... It looks like a bad king but... People seem to enjoy this stuff! Maybe cuz their your plan is clear - trade queens, bring on the endgame tactics/consolidate and grind. Very clear plan for Black, I guess...
And even if the queens remain on, the middle game normally does get quite double edged even when my first position out of book is +1.5, or +2... Let alone -0.8.
Considering the opponent is prepared for playing "out" of +4 positions, choosing a counter-attacking opening for a reason, giving him an unbalanced equal position for nothing seems like a gift Black will be grateful for (and it would be hard for me to trust myself against such a player unless I study the hell out of this position which I won't...)... a 50% win rate for Black is substantial.
That being said, I'm going to try your suggestion anyways!
I despise Pirc as White
