Personally, I would be more than a little nervous about accidentally overloading the amp.
Have you considered a setup where the signal for front left and right HT goes to its own particular input on the tube preamp? Some preamps even accomodate for this by having a direct passthrough so that you don't run into problems with volume matching. A number of preamps on the market have this kind of circuitry.
Hope this helps.
