Something I can confirm though is that the wing and engine was removed on the side closest to us to film the side shots of R2-D2.
It's around there somewhere in the nearfield of the bottom right of the image if it would not have been removed for filming
This is an interesting issue, but again I see this in a slightly different way to Ronster.
If you study the original shot at the top (without getting distracted by Ronster's mock-up below it), or watch the movie...it always looks to me that because this is quite a 'close-up' camera POV of Artoo, then the viewpoint could be imagined as being either filmed from a point-of-view that's in-between the gap between Artoo and the (unseen) X-Wing engine nearest us...*or* from a point-of-view that's actually filmed from where part of the engine would have been situated, if it wasn't for the camera being positioned there instead. Either way, we *wouldn't* see the X-Wing engine where Ronster has placed it, the way I normally look at it.
This shot below kinda gives an idea of the gap between Artoo and the engine on the real-life prop, and may or may not help to judge the camera point-of-view of the Artoo 'close-up' I usually choose to see -
On the other hand, I certainly wouldn't be against seeing a portion of the engine added, if adywan thinks it would make for a visually-appealing 'cheat'/additon. In fact, I quite like the look of Ronster's mock-up, despite not 'seeing' the shot that way normally.
I'm not sure if the *angle* of Ronster's added engine is correct...but I'm fine with the approx. height he's shown in his mock-up. Unlike Monroville's 'open-winged' pics where the engines end up higher than Artoo's dome, the wings are actually *closed* when the X-Wing is heading towards Dagobah at this point...and the top of the engines seem to be just slightly higher than the top X-Wing section that Artoo fits into.
As far as the official CGI goes, this shot gives a good idea of how things look (just hold something straight across the top of both circular engines to confirm their height in relation to the X-Wing's top section, when the wings are closed) -
And assuming these blueprints are reasonably accurate, you can 'magnify' the diagrams here to see their side-views in relation to Artoo's position - http://zabel.kiev.ua/swmodels/starwars/x-wing2sidebw.jpg
So yeah, the approx. height positioning of Ronster's engine looks pretty good to me, if it was ever to be added.
(By the way, it's interesting to note that that the R2 units protrude out of their X-Wing positions at different heights in some shots - see the 'A New Hope' CGI shot above compared to the top 'close-up' of Artoo, for example. The full-size Artoo/X-Wing 'close-ups' in 'A New Hope' also had the top of his legs showing just as that CGI shot shows, yet we only see his 'dome' in the top shot that Ronster mocked up. No biggie in the scheme of things however, as not much can be done about that)
