It's possible, but would require so much editing that it would be a completely different mod at that point. If just want cosmetic alternatives to existing weapons on each tier, I suggest using Laser and Coil Ghost Templates alongside XSkin.

i ll have a look at those sugestions.
ty very much

To clarify. i think it Is very much possible because my current setup, kinda tied things like coil to laser as tier 2 and the vanilla magnetic and beam to tier 3 because i prepared their damages and crits and what-not to be closely identical, with the only different is that coil/mag weapons deals more maximum damage and crit more damage than laser, which deals more minimum damage but is very accurate accross the board, with the end goal of making the tech a choice for a solder which of the weapon-type would suit them best. this setup of mine also works very well with me setting plasma weapon(from eu plasma weapon mod), to be the T4 and the chosen weapons(i have the hero chosen weapon mod too), to be a one-off, T5 weapons.
