Can reverse items gain stats that they didn't originally have?

For example, lets say I make a Reverse Warrior Glove. Clean with no gems/crystals/level ups, it gives +6 STR and +4 DEX. Lets say I put an accuracy and speed crystal on it before I make it. After I make it, I immediately scroll it with glove attacks scrolls, and at least one works. When the glove level ups, will it gain accuracy/speed/attack, or will it only gain STR and DEX when it levels up?

only str dex

I believe it only gains STR and DEX, because the item was programmed to only gain those stats.

It gains a pre-determined amount of stats. So, no, it won't gain any attack.

In your case, it will:
Increase STR between a minimum of 0 and a maximum of 1.
Increases DEX between a minimum of 0 and a maximum of 1.
Increases Accuracy between a minimum of 1 and a maximum of 2.

Oh. I was hoping I'd get some easy extra attack if I scrolled a Reverse glove. =/
