Primary weapon fusion for Ace?

[ForteDS]

I had a good time seeing what all is new (So far) in 30XX on twitch last night. Lots of things were showcased, like the Core Points System for Nina in being able to divert points and choosing between whatever Core Augments happened upon, rather than being forced to drop the old part in favor of the new, as well as combining her primary weapons and effectively using all of them at once. In addition, we've seen power fusions where you can use a boss weapon in a support slot for another boss weapon, and give it an extra ability or effect. This is all good stuff, but it left me wondering what Ace has learned since the last game. Since he isn't allowed to combine primary weapons like Nina, I was wondering if he could use a boss weapon as a support for his primary weapon?

This could materialize in the form of different button combination moves to give him more options with his primary, or maybe even changing the nature of the weapon itself. Something like combining his standard Sabre with the Metal Blade special weapon to give him kind of a buzz saw yoyo, or the tornado weapon to give him something like X4's Rising Fire? Maybe combine the Mortar weapon to give his charge attacks an explosive finish when striking the ground for some splash damage? Ace had his Sabre, Plasma Blender, Axe, Spinning Glaive, and a Spear primary weapons. Assuming that there are no new weapons, or some were switched around but the total weapons remain at 5, with 8 bosses and 8 special weapons, there would be 40 weapon combinations plus null to consider.
