What I would do is use the Boston Acoustics speakers for your main mixing and use the Hitachi's and/or the Altecs to see how translation is.
Lots of great producers and musicians have mixed on home stereo speakers, Todd Rundgren used Klipsch Heresey's to do his mixes in his studio and Tom Scholz mixed on Cizak home stereo speakers for the first 3 Boston LP's, they were audiophile grade speakers though....
I have a set of Pioneer CS J525 home stereo speakers, They have 2 woofers and a tweeter in the middle, they are really accurate so if you can find a set(They're pretty hard to find) grab them!
I have 4 other speakers I test mixes with, on my desk I have JVC bookshelves, Harmon Kardon computer speakers with a sub, and a set of HUGE Cerwin Vega High energy design speakers from the late 70's. The other set is my car speakers.
