Yeah you give to you other chance, sure you make a good work, step by step the remaster comming ehehe,
all you need for no use brand mint is, remove software center and all icons or themes with the brand of mint and of corse if have a program made by tema mint you need remove, after this your remaster is based on mint but is a creative work made by you and you can share your remaster for friends.
Im use the gnome 2 i like more than Unity, or cinnamon, or gnome 3, ->
is possible make a remaster with gnome 2 with installation of gnome-fallback and edit gnome session default (you cna edit name and type of gnome session)
You can make you plymouth, your lightdm custom, your icons, everything.
If you can try dont exceed 4gb in your remaster because remastersys can give errors and burn image in a DVD is even to 4.7 GB.
I make 4 remaster well succeed, and is a good method to spread Linux and SL, remasterys is absolutely primary tool He is equal to Quality, simplicity, Speed, and amazing efective.
If you want spread your work for others users you need use a method to host your iso, the easy method for me is torrent, because Megaupload and other sharewares method are off, use any hosting or link torrent.
If your project need you can create a derivative page in Ubuntu - https://wiki.ubuntu.com/DerivativeTeam/Derivatives -
My Flavitu Linux have one devirative page to inform people about project.
