Given that there's a forum dedicated to Conversion revolvers - with numerous threads - I'll point you towards the 'STORM' forum.
While there's some information here on 'Frontier Iron' - there's a lot more on 'STORM' that'll be most helpful.
For actual historical information on Conversions - read McDowell's fine book - 'A Study of Colt Conversions and Other Percussion Revolvers'.
For 'pretty' - read Adler's - 'Metallic Cartridge Conversions'.
Good Luck!
