Absolutely. The only reason you need secondary audio set OFF to bitstream is that the Panasonic doesn't have Dolby TrueHD or DTS-HD *encoders* (it has decoders), but this is not unique to the Panasonic players. No BD players have DTS-HD or TrueHD encoders.
In order to be able to mix the secondary audio feed (which is normally PCM) with the primary Dolby TrueHD or DTS-HD bitstream, the player would have to be able to encode the PCM signal to the native format, then mix these two audio tracks together to output a new Dolby TrueHD or DTS-HD bitstream. Can't do that without an encoder.
On the other hand, if you let the player decode the Dolby TrueHD or DTS-HD track to PCM, then it can happily mix in the secondary audio track and output this as part of a newly remixed multi-channel L-PCM track.
Make no mistake, your beautiful Dolby TrueHD and DTS-HD lossless tracks *are* being decoded to PCM before they are converted to analog. PCM is how they started life in the studio - they're converted to Dolby TrueHD or DTS-HD simply to save bandwidth. It's just a question of whether you want to decode to PCM in the player or in the receiver. If you decode to PCM in the player, then you can still access the Secondary Audio track on BonusView content while enjoying the lossless audio.
So the answer is yes - you can have your lossless cake and eat your secondary audio track too if you use PCM output over HDMI or multi-channel analog output from the player.
