OK first thing, can you share the contact info of these Qatari local makers or sellers?
For serious expeditions/overlanding they are not preferred, but for a biweekly dune basher , they should serve the purpose and as you mentioned, no need to upgrade the suspension and you are good to go. Any aftermarket steel bumper is no less than 40kg !
Also the problem with ARB, TJM or whatever brand sold here, doesn't sell their bumpers accounting for the LC200 fitted with stock Toyota OEM winches. A couple of my friends with stock OEM winches went with TJM and had to go through some serious alterations and fabrications !
I wish to keep my stock winch and avoid the fabrications .... hence the search continues....
