Is there anything I can temporarily stick in the exhausts to lower the emissions, like a banana skin, absolutely sure they wouldn't notice.

The DNA filters themselves won't necessarily make the emissions worse, if you have no fuelling mods (?), then if anything it might be cleaner/weaker. If you have a fuel mod and you're worried you could always turn it down (or off) to weaken things up further just for the MOT?
As for the exhaust, I guess it depends whether a catalyst IS required in Japan for the test? If it isn't you'll be fine, if it is, then you'll have to go back to stock or get some cat inserts for the Leo Vince (is it Leos you have?)

Sorry, but can you explain what a "semi solo" test is in Japan? Why is it more strict?
