MAy or may not be a good trade off depending on where you live of course. Biggest question is what speeds do you normally coast through turns?....

If you're getting wheel spin, you're accelerating too hard. I don't think many ecomodders are driving so hard that wheel spin is a regular occurrence.
Likewise for braking, it will only affect emergency braking, as one of the main ideas behind hypermiling is driving without brakes as much as possible, so hard braking will likely be a rare occurrence.
And for turning corners, there is little reason that LRR can't turn as well as standard tires, as they reduce front-back rolling friction, not side-to-side. I know that some LRRs are not as good as some normal tires, but there are also plenty of standard tires with sub-par turning capabilities.
