McGiver does it all the time and finds alternatives but that is a personal choice . imho adapting the coil or the base is not likely a reason to worry about reliability if that is your main concern.
Case in point most folks replace outboard rectifiers with OEM eqpt at a high price.
Rectifiers are simple 4 way diode bridges and you can buy a high capacity 4 way bridge rectifier for 3-4 dollars …. but it does not come with a fancy molding and mounting hardware leaving room to imagination as to how it can be fitted in…. but it is still a rectifier.
