I know GP is edible, but client really wants to EAT the topper (without losing her and husband's teeth 
). Would fondant with added tylose be strong enough? I thought of using marzipan-fondant mixture but would prefer not to. How to achieve this type of face, also the bike quite worries me...

(I know, they are quite disgusting 
but client's wish...)
Anybody could give any advice? I'm deciding if decline this order or not. Thanks a lot!
You could try adding tylose to your fondant or a 50/50 mixture of fondant and gumpaste. It might be a good idea to make a small figure with one of these to see how hard it gets and how likely it is for the whole topper to keep its shape. On the other hand, you might just have to tell them that you don't always get what you want in life. And yes that is one ugly topper, but I'm sure you can make something lovely out of it!
Fondant with tylose is going to dry hard like gumpaste. It takes longer to get that hard, but I have some figures that done after a week, they are pretty hard.
If you want edible I would go with straight marzipan or modeling chocolate. Both will also give you more working time to create the faces as well.
Now see, that's what happens when you live in a hot, humid place with no AC in the kitchen like I do. I can't really get gumpaste to harden like it should, much less fondant plus whatever! But thanks for the tips about modeling chocolate and almond paste ladies - I'd like to try them sometime to see what they do here.
Thanks everybody so much for the replies! I e-mailed the client asking about any type of allergy (nut allergy for marzipan) and gave her a 'nice' price . Let's see. Checked my molds but nothing resembling a bike... Don't know about modelling chocolate as I suck at it.
