2 Battle Systems

Hello there, I'm new here 

Is there a way to use 2 battle systems???
In the normal gameplay i want to use the Sideview Battle System Tankentai XP

and in some other battles i want to use the GubiDs Tactical Battle System v1.4

No, you will need to do alot of scripting.
But you can make the tactical battle system using events. (but it's hard)

crap 
i know it might sound foolish(because i can't script) but isn't there a way to make it with switches
for example:
when switch 1 then sideview
when swiitch 2 then tactical battle

what i mean is to turn off one system and to turn on the second
(sry for my english^^)

My mind is telling me know, but my heart is telling me yes...

That is to say, I am fairly certain that there is not a way, but it is just glorious enough of a hope that I think it can be done... I should learn this... RGSS system... It might prove useful in situations like this...

You might be able to turn one or the other on using switches, but I'm unsure.
