Dunno, seems a bit odd to me. Not to mention perhaps a bit annoying for anyone who did buy the original physical version.
Besides, wouldn't something have to go away to fit 'Mechs? Think someone said the TRO CI doesn't have some of the classics for example.
I'll further note that i'd like consistent art (style) across a TRO. Currently, more or less all TROs do that, except SW and CI due to their nature as compilations.
Perhaps a special TRO framed from, say, the Kickstarter perspective, featuring 'Mechs in the KS, plus the Elemental Battle Armor. Hell, make it portrait orientation, full color, and POD-option.
