Can the Masque of the Red Death survive Strahd?

I am playing with the thought of running CoS in a victorian setting, using the Masque of the Red Death, Gothic Earth 5e rule set. My players are kinda on board, but can't really have feel for the impact this will have on gameplay experience. And frankly, neither can I. At first glance the Masque of the Red Death player's guide provides great tools for roleplaying in a gothic horror setting, where fear of the unknown and fear of dying play a big part, and magic is mundane but tainted. Therefore it looks like the ideal expansion to facilitate the feel of horror in CoS. Mostly I don't want the PC's walking through Castle Ravenloft with the feeling that new health and HP is just around the corner. The question is: will it work? Does anyone have experience with either running or playing CoS with the Gothic Earth ruleset?
