In our dojo, we add kendo kata to our MJER waza, as well as tachi uchi no kurai. I think both of those certainly help our tekki visualization, although neither are, of course, randori.
Kendoka, on the other hand, have free-sparring, but don't use a sword (before I get jumped on, a shinai simply isn't used the same way as a katana - just consider the very limited target areas).
