Just by looking at the picture, the rep dial doesn't look bad at all (the minute markers are the same width from beginning to end on the rep dial whereas they are not same width on the gen dial). The Arabic dials are quite simple in design, I would hope the rep factory can make it right.
When people franken their BCEs, they are likely keeping it I have only seen two people selling theirs since I joint RWG. If you want a franke BCE, you will really have to get it done yourself. I mean getting all the parts needed and having your watchmaker do it. I think the procurement process is kind of fun personally. It makes you appreciate the final result a whole lot more.
Since you already have a stick marker dial BCE, I would consider to get a gen dial using the $$ you would purchase another rep BCE if I were you. Keep an eye on Ebay, sometimes you will find a good deal. I bought all my dials and bezels there.
