What about buying a 7th gen sedan manual for about a thousand and having a cx tranny & kill switch installed?
A 7th gen sedan swapped with a CX transmission and a kill switch is also a reasonable idea. But a swap into the 7th Generation would be slightly more complex than one between 5th and 6th generation cars because of the electronics that were added to the 7th gen. There are guys have done it. And if you follow the link to my manual transmission specs thread in my signature below I believe I have a link in there under the 7th gen specs that will lead you to someone who attempted it.

But imagine a little bit more how you might drive the hybrid. It has final drive gearing in between where a VX transmission and a Sixth Gen HX. So even if you disable the Hybrid battery you'll have a car with really tall gearing even if not quite as tall as a 5th gen VX or CX. However, with the hybrid and the bypassed battery you have an engine that is much smaller than a standard 7th gen engine and it's even significantly smaller than the 5th gen 1.5 liter engines. That means that doing pulse and glide with your very tall Transmission and your very small engine, you should be able to get some really remarkable numbers with the kill switch installed.

Just an alternate suggestion.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
