Yes, even without shields Reapers are extremely dangerous but if you have enough forces, you can easily overrun them with sheer numbers in that scenario. If you managed to gather the best fleet you could, I'm pretty sure they could pretty much decimate the reaper fleet., albeit with heavy casualties.
