MODX TinyMCE used externally?

I am converting a site to MODX Revo, but have a couple of legacy components from the old CMS being loaded into a CMP using an iframe. This is only temporary as the budget doesn’t allow converting to a full CMP for MODX yet.

The only change to the old system is that they would like to have a WYSIWIG editor on one field. I could easily just download a separate instance of TinyMCE and use that on the form, but I’d like to use the same version that’s being used for the main content editing in the manager.

Is it possible to load TinyMCE on other non-MODX pages like this?

Also, I’m aware that I’d need to load the main functions by using the code from http://rtfm.modx.com/display/revolution20/Loading+MODx+Externally

Thanks for your help!
