Possible to change a unit's attack type?

I've gone through alot to try and get this done...

I need to change a unit's attack type, for extra information, it has to be switchable back and forth, the unit is not a hero and I CAN NOT REPLACE THE UNIT WITH ANOTHER UNIT TYPE!!

I've tried using upgrades to disable a unit's attack 1 and enable attack 2, however this only works once.

I've tried using the orb abilities but that enables BOTH which is what I don't want.

So if anyone knows how to do this I'd appreciate it... I'm willing to use JASS if I have to or just about anything else to get this done.

Well, you could jsut use a morph spell, but if you insist...

Set attacks enabled to NONE.

Modify an orb spell to enable attack 1 and give no other bonus.

Give the hero this orb ability when the hero is created.

Use a dummy spell to switch.

When dummy spell is activated, replace the 1st orb ability with another orb ability that enables attack 2.

Damn I never thought of that. Thanks.

Edit: What ability should I use, when I use orb abilities when ever the unit attacks ground the game crashes.

Umm use the new lightning orb skill. Try leaving the casted spell as it is but change the chance to cast to 0%.

Make sure both your attack 1 and attack 2 are set up properly.
