Upgrade-path? [classic -> pro]

Hello,

Just joined the fourms to ask this question, sorry if it's been asked in the past.

Is there an upgrade path if I first buy a classic midifighter, then later decide I want a pro?

For example, I could mail the classic back, and the buttons could be transferred from the classic to the pro?

Or perhaps the parts of my classic could be refurb'd and I could get the pro at a discounted rate?

Thanks in advance for any insight on if there's such a program.
