I got it working to an extend at least,  
all the custom values/variables for the config files need to be made.  
All the commandline options need to be setup.   
After tinkering my alterations tcadmin downloads SE from SteamCMD, installs to the "username"/"server number" folder, 
and successfully boots up a server in 64bit mode...    
Now i'm just taking care of world/config/environment locations and command line options, if someone has that one down I can combine and upload.   
Next step would be making a interactive configuration  
(the nice tca form way)   
Last step for us would be creating a mod for that gameconfig so you can install server extender MOD API in one go.  
(obviously having a form to setup configs, game mods/workshop items and backups etc etc) 
ServerExtender allows for a webinterface (rcon style) and commandline worldfolder setting, i'm unsure if the same commandlines work for vanilla executable.
