From the qt-core-4.4.2 ebuild:

RDEPEND="
!<=x11-libs/qt-4.4.0_alpha:${SLOT}
"

Te first blocker you have does NOT refer to any version less than 4.4.0_alpha, 
it means any version less than that which is SLOT=4.

Fixing this is simple:

unmerge the existing qt:4
merge qt:4

They all co-exist nicely with qt-3:
