Leeway Composites (member on here) also do a console of the size you're looking for, but it may be too low for you?
Which Outhill console are you interested in? Ribquest have developed their own console, which, to me, bears a remarkable resemblance
to one of the Outhill consoles, so if it suits you, they may be able to make one for you.
Humber & Solent also produce consoles 'similar' to this.
