Maybe in 3-5 years.

Don't the Flyers have Ghost, Hagg, Provorov, Sanheim, Morin and Myers? And then MacDonald/Gudas under contract for next year as well. They also have Zamula who had a prettttttty good age 19 season in the WHL. Seems like a pretty good core that would have Fleury as an AHLer/7th dman in the NHL for a long time.

Always nice to have depth, but I can't imagine them trading that offensive potential for Fleury and a 5th.

Need a sniper on the left side on the Suzuki line. Who else ?

If you're not going with Philly specifically, signing Duchene is certainly an option. Apparently he turned down $8x8 (but that might have been in Ottawa, so who knows...), but I don't see why he couldn't be a realistic target. He's played both C and LW, so it'd be a good signing to ease up some of the load on KK/Suzuki. It won't be cheap, and who knows if he'll come back to a Canadian market, but it makes some sense to me.

If you're only looking at young, cheap players though, it's going to be tough sledding. Why not look at internal options like Tatar/Drouin?
