Do I really need two power switches?

[glassdoctor]

I'd run it a while before doing any modding...

And I would keep the switches just for convenience. For example, if you are ever racing.... you can plug the battery in, put the body on while waiting for your race, and then just flip the switches to go. It's really not a big deal... as you can just use the battery connection as the primary "switch". Really, you can solder up both switch leads if you want.

ps: I have removed or replaced the swithes on my MM because I have had them fail during races... :( but assuming the switches work properly there is no reason not to have them.
