Does any A/E have the "thump" ?

In a word, no. The RAs, Godins and their ilk sound more or less like standard bass guitars, with just a little more airiness or "stringiness" to them. Same with most upright electrics, the exception being those instruments that adhere more closely to standard doublebass construction, eg. Azola's Baby Bass and Bartig's Eminence.

 

Well, Ihavre to agree there, but with one caveat. I play a Godin A4....which is one fantastic bass, and for the money hard to beat...and with Thomastick Acoustic strings am able to get that sort of "thump". But, at best, it is merely an emulation of the upright sound, and I choose only to use it when I need it...like acoustic jazz tunes, and then I TRY not to sound too much like an upright (technique-wise).
Most of the time, I use my Godin fretted A4 with TI Jazz Roundwounds just for that "airiness" which imparts a slightly different tone than the rest of the solidbody bass crowd.
In short...to get a real upright sound, play an upright. That's probably not what you wanted to hear, right? (and I must second that endorsement of the Azola Bass.....great instrument!!!)
Oh, and then there is the Turner Renaissance, which is capabale of some incredible "upright-like" tones.....
....but, this is just my personal opinion, I have never treated the "horizontal" bass as I would a "vertical" bass. To me the bass guitar, including ABGs, are a diiferent animal than the upright. And tho I gravitate to some "acousticness" in my tone, I do treat the bass guitar as a bass guitar and not as the horizontal equivalent of the upright bass.

I think the scale length has a lot to do with it - so things like the Steinberger Electric upright with it's 41" scale length sounds more like a normal double bass than any "acoustic electric" , even though it is solid body.

I think the hollow body thing is just a gimmick inpsired by the MTV unplugged phenomenon.
