You could and I've done that for awhile with my DPL HT setup during 1997-98.
Once I timbre-matched everything (1999), there's no turning back because I finally experienced what 100% DD/DTS discrete 20 Hz - 20 kHz 5.1 seamless surround effects / sound is, ... and its glorious with my identical speakers in the Front & Surround locations (w/timbre-match Center Speaker of course! and powersub)
