Great if you can swing it but be forewarned, very few companies will allow this if they know what they are doing, apparently this caused nightmares leading to Facebook's IPO due to a bloated term sheet and very few companies will explicitly allow it if they want to eventually IPO. I wouldn't expect them to go along with it and it might be explicitly forbidden in your contract.
