French infantry in colpacks or Nassau Grenadiers (same thing in 6mm) for Naps. Swedes in 6mm for 1813?

I could also be tempted by Indian mutiny/ Sikh wars British and Indian troops. Colonials for 1840-60..

Indian Mutiny/ Sikh wars and Colonials would be good, and Crimean War too!

For Colonials:

Heliograph set (maybe as part of a camp set / engineers?)

Egyptian Cavalry (and dismounted)

Egyptian Camelry (and dismounted)

Sudanese Lancers

Bashi Bazoukhs

Egyptian Krupp Guns

Hadendowah Riflemen

For "Naps. Swedes in 6mm for 1813" you can probably get away with using proxies like...

• Russian Line Infantry (most started using the Russian kiwer, a few used the French shako and almost none retained the older style traditional Swedish round hat despite it still being regulation)
• Spanish Hussars (in mirleton)
• French Line Artillery (in shako)

Luckily you don't want to do the war against Russia in 1808/9, because then you would need all the infantry and artillery in round hats!

Resurecting a thread here but would agree with all of the suggestions above re colonials from Nick and Matt plus the addition of Naval landing brigade, i have some acw skirmishers i am going to try and convert, as whilst H&R do this i fear the scale difference will make them look worse than my attempts at conversion. 

Open and closed coaches with Marshals and Generals.... Thinking of Massena's Phaeton here...

Walking Marshals and Generals, leading the charge... (for those countries where applicable)

Any news on when / if the Egyptian cavalry, camelry artillery gun crews might be making an appearance? My Khartoum Project is crying out for them ;)
