You can use bar end shifters on the down tube braze ons, but you need the other bits that may be very difficult to source. A set of dt levers will only cost a few quid, so it's not worth trying to use what you have for the sake of it. That said, Paul thumbies would, even at £49.999, be worth it to keep the gear changing on the bars.

For flat bar brake levers, a pair of low end shimano jobs are fine.
