Thats only if the reaction is automatic (such as attack of opportunity even tho in the TT version, you can actually choose to make one or not, as you only get one per turn and maybe dont wanna waste it)
That beeing said, reactions in 5E are vastly toned down from 4e (where they include things like shooting someone on their turn to decrease their chance of hitting an ally or literaly giving an ally an off-turn move to reposition themselves which obviously makes no sense in RTWP)
i personally dont think the action economy of move and standard actions "dont work" in RTWP, but movement works in a very different way.
Inspiration would be an odd thing in RTWP, but it would work since it only affects the next roll you make, rather than beeing a reroll mechanic (Such as edge in shadowrun).
You make good.points
