I'm sure within enough determination and with solid enough parts anything is possible, but I highly doubt it would be worth the effort\money to even try. Anyhow get the lightest spring they have and just grow into that. .
The totem is one sweet fork but its made for the above average rough rider and for some pretty big hits and drops. If you are not yet that type of rider you might consider selling it as is, and replacing it with a more appropriate fork.
Good luck man
