I applaud your step UP! Also to see more interest in the fascinating period and conflict(s).
I like the Front Rank range myself, but my Jacobite armies are now vintage and include all sorts of figures from all sorts of companies, many of which are no longer in production. And when I began seriously (mid-80s), there was very little available to choose from, in any scale.
I was obliged to force into service mostly Seven Years War British troops (mostly MiniFigs) and all manner of Scots, some from ECW ranges, some from SYW ranges, some older MiniFigs from their long-defunct Jacobite range; eventually I was able to replace some less desirable castings with better ones. But to this day, it can be a challenge to obtain some of the more off-brand figures (e.g., Baggot's Hussars) and good Commanders, or civilians, or proper artillery. But it can be done.
Then you have the fun of painting all those tartans! Go for it!
BTW, what rules are you using?
looks at a multi-period building.
