It is possible to do a pretty good job of disguising it, it has its limitations of course but most people wouldn't notice until you get less than a meter away.If you want replica period sashes then forget double glazing, it's totally incompatible with trad design. Instead look at having internal shutters or secondary glazing, or even just thermal blinds.
It's a compromise but can increase the warmth noticeably in conjunction with draughtproofing.
It's not perfect but if you need new sashes anyway then it won't hurt.
