Wired glass is expensive – it’s made using a rolling process, not on a float tank.
There’s an on-line calculator here:
https://www.betterglass.co.uk/shop?order=name+asc
that puts your single largest piece at £183+VAT for Georgian (obscured) wired.
(By way of comparison, 6mm toughened is £62+ VAT for the same size, 6.4mm laminated about £50+VAT )
If you want expensive, try polished (clear) wired! 😀
Can you stick frosting film to the existing glass?
(ETA: I’d say laminated is a PITA to get through – though not as much as wired – so may give more peace of mind than plain glass).
