MAS makes epoxy right? So you're using epoxy -thats good. When you glass the skin onto the piece you'll get a sense of the gel time. It won't change by adding filler. However, my experience is that afternoon gel times are much faster. I was starting my work in the morning at 70-75 degrees and by afternoon it was 85+.
Make a test batch of adhesive so you can guage the time and how much you need for the whole job. Its going to be a lot for a piece that size. You might want to mix multiple containers because larger batches get hot and kick faster.
But you will be pouring the whole batch onto the piece and spreading it quickly so that may not be such an issue.
I still suggest using a few well placed screws from the top to help hold the piece in place. Pre-drill the top skin and the screw will pull up the working piece. The holes for letting some squeeze out is an excellent idea. Just be careful because you are under it!!
Hmmmm? 70" x 40" is pretty big to hang upside down... I would think about cutting in 2 or 3 pieces. Smaller piece in the hard to reach area and gain experience with the process...
