My thoughts are, take some shine off off the vocal reverb (If your reverb lets you EQ the verb, pull down the above 4-5K area and maybe EQ out below 1K). You're right, a bit muddy, but I think if you worked the EQ on the source vocals, pull down the 250 HZ area (sweep to find you area), I think the mix would still be to your liking and not sound muddy.
