Hi,
technically, you should be able to make it fit.
Please mind the different loudspeakers: VBar Control EVO has had changes (and a product recall) because of a distance issue between the back side of the main board and the speaker, in early summer last year.
All is well now, but please make sure you use the low-profile speaker from EVO, to make sure it certainly fits, in any case, check-make sure that there's a gap between the two, and that it's properly insulated.
On a side note: we do not recommend disassembling our products beyond what's explained in the manual (change stick mode, replace battery, replace a broken switch, such things). Any damage which occurs during such modifications is no longer covered by warranty any more.
Kind regards
