Something unusual, Move Admin

Hello Developers,

I have a very strange an unusual question 🙂
My BIO: I can hardly write a code (the real one) and not familiar with WordPress at all (maybe little)

I’m running WordPress Multisite network (subdomains) with WP-Ecommerce plugin.
Now I want to move all of the WP-Admin to one particular subdomain blog where I also run buddyPress plugin.
for instance if my network is example.com, I want to insert my products from admin.example.com
(but in future I also whant to insert usual posts)

Here are 3 solutions I came up with:
1) make some iframe with wp-admin add product page
2) Hardcode “Add Product” query in my code (sounds like best option for me but don’t know how it will affect my other plugins)
3) Move my site (buddyPress) to WP-Admin 🙂

any more ideas? other thoughts? Suggestions?
Anything is accepted, as two heads is better then one (little bit ugly though)

Thanks
