Is this game not mod compatible?

From what I understand coders are looking at MEA currently so see about modding possibilities. The structure of the files is nearly identical to DAI, and the file formats are identical, so in theory modding it should be possible. I'd expect textures, hair edits, armor swaps ala Live Like Viv or the like (a mod that allows the Inquisitor to wear Vivienne's clothes, Dorian and Sera have one too.), and bare bones romance mods. Possibly power and class (or profile, whatever) edits, that kind of stuff.

Right now what can be edited in Frostbite are ebx files, plot flags (so, the romance mods, basically), textures, and original meshes. True, full importing of meshes still hasn't been achieved (if you've ever wondered why most of the available hair mods are so...well, underwhelming, it's because no one's figured out how to import a new mesh or an edited mesh that has more vertices than the original. Hence, all mesh mods must be a very very carefully edited version of the original, with no changes to the basic structure.) So I wouldn't expect new models of anything, guns or armor, other than making previously unplayable models equippable by the pc through ebx model swaps or the use of Cheat Engine.

All that said, Mass Effect modders have managed to achieve a lot in the past, and imo the mod community tends to be more tech savvy, in a coding sense, than the DA community, for whatever reason. So I wouldn't be too surprised if this is the game where people finally crack some of the trickier issues modding Frostbite presents, but I still wouldn't expect anything near on par with what's achievable now in the old trilogy.
