Wood and slab side table

Not complete, but a concept I will be doing with another.

Would appreciate any advice.

In the 1970's Dutch Elm Disease caused all of the elm trees on the land I lived to die.  A good friend took slices of the bases of some elms and made furniture from them.  
I have a beautiful, coffee table and a smaller, side table.
The side table is about 2' wide.  It has a satin finish.  

My friend and I want to transform the side table into something more beautiful.
This will be somewhat of a first for both of us.  He has more woodworking experience than I do.  i am well versed in rocks and use of polymer based sealants.   I also know how to utilize glass table tops and add electric/battery lights.

So, we want to transform my table to include a slightly elevated, glass top that contains various rock slabs.  Include a LED light strand  on the outer edge of the slabs or slightly under them.  The lights could be turned on and off.  

The rock slabs would only be on the outer edge.  That would leave about 1.25' of the elm top to show.  
The glass parts would be elevated from the elm top by about 2".


So, any advice?  Any flaws in our thought process?  

Thanks
