I recommend you do both, but
don't use the Hipshot Trilogy, because that's just a mechanism to allow you to change tunings on the fly, and you
can't use it to change chords while you're playing. I have an Essex lap steel that I fitted with
Duesenberg Multibender palm levers, and I use it a lot. There's no set-up time, compared to a pedal steel, and you can get pedal steel sounds from it. For what you do, it would word perfectly. You can just grab it and take it out to a gig.

I don't have anything against the Hipshot Trilogy, and I have two of the 8-string versions installed on lap steels, but it just allows me to use different tunings. Other people use them on regular electric guitars for the same reason. But they wouldn't do much for you, and you can't install both a Hipshot Trilogy and a Duesenberg Multibender on the same guitar because they're incompatable.

(I've tried it.)
Personally, I don't see the point in combining regular and lap steels. You can have both on stage side-by-side, and pick up whichever you want to play. With two separate instruments you can get both of them set up exactly as you want them, without the compromise of having another instrument glued to it. It reminds me of those 12-string/6-string double-neck guitars which are just an incumbrence, but, each to his own, and I don't like to hinder innovation.
