steps support weight of cab w/doors + glass?

[59chev]

I need to pull my cab off the frame. Instead of lifting the cab, I plan to build two dollies under the length of the cab steps then drop the frame out from underneath.

My question is can the steps support the weight of the cab with the doors and glass installed? There would be two 2 x 4's running the length of the steps on either side of the brace underneath the step. I don't otherwise have a need to remove the doors and I would like to avoid it if I can. I just finished welding in new floor pans/braces/hinge pockets so the cab should be structurally sound.

Any advice/pics of anyone who has done it this way would be appreciated.

Thanks in advance.
