  At least, You need a downconverter from 2.4GHz to 144MHz, and a 2.4GHz
antenna that has 20dBi or more gain.
  I do not know how much gain of your 435MHz Yagi, but I tried to QRV
by 11-ele clossed RHCP YAGI with 20W diring last AO-40 test operation
and it works fine. So maybe your 435MHz Uplink system will enough.

  But, what the IF band of your 70cm transverter? Which Is it from HF
or 2m? If HF, it is OK. But from 2m, you will be in trouble of IF freq.
