Doomsday Engine

I imagine the summary is probably very vague, but I couldn't think of a better one.

In Doom and Doom2, there is an unused sprite, SMT2A0, of a grey stalagmite. This sprite is attached to an unused state called "STLAG".

Skulltag, followed by ZDoom and other decorate supporting ports added a mob def for this state and sprite:

ACTOR Stalagmite 5050
{
    Game Doom
    Radius 16
    Height 48
    +SOLID
    States
    {
        Spawn:
        SMT2 A -1
        Stop
    }
}

How likely is it that Doomsday could do the same; I’m mainly thinking of cross port compatibility?
