Got a solution. And it's even very straight-forward and can be done with remote registry edit, too!
code:
[HKEY_CURRENT_USER\Network\O]
"RemotePath"="\\\\server\\share"
"UserName"=""
"ProviderName"="Microsoft Windows Network"
"ProviderType"=dword:00020000
"ConnectionType"=dword:00000001

I exported a example mapping from HKEY_CURRENT_USER, changed the drive letter in the registry key, used a different RemotePath, and reimported the .REG file back into the registry. After hitting 'Refresh' in the Explroer, i had the additional drive.

Give it a try, you should be able to write to \\COMPUTER\HKEY_CURRENT_USER, too.
