Hmm...well, a "Frame" could mean a lot of things, honestly, and this is actually internally referred to as a "Thought Armor" due to its control system the the removal of the pilot's limbs from the Armor's limbs. I'm not sure how similar this would be to Osakan's frame at all, so I'm steering clear of that term for those reasons.
I do know the end goal is a machine that's notably smaller than his WINTER (just checked), preferably LAMIA sized.
Yes, cramming a person in the chest alone of a LAMIA chassis will be a distraction in combat to the pilot due to discomfort, but the Beta series will be dealing with that issue.
Edit: I feel some people may be confused about some things, which I will clarify.
1. This Armor and its components are the earliest prototypes of the Thought Armor. As such, it's meant to have the cockpit flaws, and we will never have more than 1 in existance. It will never see combat, its weapons are all mockups which don't fire anything, and its sole purpose is R&D; specificly regarding the limb and head joint designs for the Beta series (To Be Designed).
2. The remote control module is useless in battle and would not be a final feature of the machine. It would be an emergency measure to allow the LAMIA Agura to continue testing, without the stresses of discomfort on the pilot from the cramped and faulty cockpit.
The remote control system is a reprogrammed comfort bed, and a pair of simple components bolted inside of childrens' lunchboxes in a hurry -- it's meant as a stop-gap measure while the Beta is designed with a more tolerable cockpit. As such, the remote control system is not a goal of the project, nor will it survive past the Alpha stage.
These are things meant to RP the R&D of the final product, and are not actually what Project THOUGHT will come up with as a final product.
