Help with brake lever/aerobar compatibility

I bought levers (Bontrager - http://trekstoremadison.com/product/bontrager-xxx-aero-brake-levers-50916-1.htm?gclid=CMiksqKwt7sCFe3m7AodjBkAEw) and an aerobar (deda kronos, see pic below) not realizing they may not work together. The aerobar does not have routing for the cable to enter under the bullhorns. it does have an exit on the backside of the aerobar. The levers I got however route the cable outside the horns, so there’s no way to route them internally. I assume I need a lever that will route the cable straight into the inside of the aerobar.

Can someone help me figure out which levers will and will not be compatible or if there’s something I need to look for specifically? I want to buy something reasonably priced (used, here or eBay) and aero, but not sure makes/models to look for. Drilling a hole in the aerobar isn’t really an option because i couldn’t route housing through small holes. It would also be great is someone tells me an idiot and I’m doing something wrong.

Thanks.

If you don’t want to drill (understandable), then you need levers with internal routing like the Bontrager RXXXL Aero, or Shimano BL-TT79 (DuraAce) as a couple of examples. Magura RT-TT brakes also route this way as do the Campagnolo EPS brifters, but obviously either of those requires a much larger change in your component strategy.

Does anyone know if these route directly into the handlebar? I can’t tell from the pics or descriptions:
