I had an idea of how Hasbro could finally get Multiforce/Landcross into Generations and the answer is here:

That's right, the answer to getting Multiforce into Generations is combining it with Energon for a full on line wide double combiner line (similar to what we previously saw in the likes of Combiner Wars and Titans Return).
The idea is that some figures would either be based on the Multiforce characters and repurposed into an Energon character while others would be based on Energon figures and then repurposed as a Multiforce character. This would include Decepticons being able to "Powerlinx", too, and with enough repaints (everyone loves endless combiner repaints!) between mainline, Selects, and store exclusives we could possibly get Landcross and Energon Autobot and Decepticon combiners. Here's what I'm thinking:
Multiforce and possible retools-
Wing -> Starscream
Waver -> Decepticon Mirage
Dash -> Hot Shot
Tracker -> Snowcat
Mach -> Jetfire
Tackle -> Ironhide
And the final six-
Inferno -> Demolisher (dumptruck)
Prowl -> Cliffjumper
Sharkticon -> Sluggslinger
Don't ask me how they would combine, I'm no engineer. Some of these could probably be unique molds, the real focus is on those first six. But that's nine base molds for 18 figures and three combiners. It would take care of all the figures for a three wave line and then some. Scale be damned!
Oh, and paired names:
Hot Shot + Inferno = Hotferno
Jetfire + Ironhide = Firehide
Prowl + Cliffjumper = Prowljumper (??)
Starscream + Mirage = Starrage
Demolisher + Snowcat = Democat
Sharkticon + Slugslinger = Sharkslinger (!)
