How much experience do you have with ye olde Synergy Drive?
What mods are you going to do?

I have about 1,500 miles of highway experience thus far (basically from the place I bought it to my brother-in-law's house to my house.) But that's it! Any suggestions would be helpful. I do a lot of highway/mountain driving.
One thing I really like so far about the Avalon is the shifter. I noticed that the battery filled up really quickly going down a mountain pass. But the shifter gives me 6 selections of engine braking. I can go down 8% grades without using the brakes. Nice! Overall, I love how it drives!
I would really, really, really like to increase the battery capacity somehow and make it a plug-in hybrid. Even if the engine starts a bunch, if I could increase my mpg to, let's say 60mpg, that would be awesome! A bigger battery could absorb the energy I normally bleed off braking going down mountains and be used to go up the next mountain. However, I don't want to spend a fortune doing this but I also don't want to do a hack job either. I see that there's a company called Enginer that makes plug-in hybrid conversion kits. But they're not cheap by any means. Still, very tempting.
But first things first, I want to install a engine block heater first. If I could figure a way to install a heat tank system like on the Gen 2 Prii, that would be awesome! Something else I'd like would be to find a way to heat the battery up to normal temperatures during the winter. Wheel skirts and radiator shutters would be nice too. I guess I need to get ahold of a Toyota Dealer to find out what block heater is available, although a 1,500W circulating heater would be best in my opinion. I'd have to figure out where to install it though.
Other than that I want to figure out how to maintain the car very, very well. The longer the car lasts, the better. I see the owner's manual says to tighten the chasis and suspension nuts and bolts every so often to the recommended torque specifications. But I don't know what those specifications are and they aren't in the manual. I'm contemplating a transmission flush, brake flush, and a radiator flush some time soon. Also I don't know how often the timing belt should be replaced. It would be nice to rack up some 700,000 miles or so like I did in my ol' Golf.
A CNG conversion would also be tempting, especially if I could fill from home natural gas at around $1.75 per gallon equivalent. However, there's quite a few obstacles that I'd have to overcome. Maybe someday, but I'd rather tackle a bigger traction battery first.
