I don't see why not - you can give them access to the company, you should be able to give them access to ttadv0140m000 to change their current package and VRC. You might(not sure about this) have to give them some developers rights - but you do not have to give them access to the development sessions. So I think you can, but we do not do this.
My latest mantra - make sure you have latest stpapi patches and the latest session object. If on LN then please explore the option of using DAL2 functionality.
