Doesn't seem like embroidery would be that big a deal. Convert the bridge to a solid light blue and the rest is just basic embroidery.
Unfortunately, that isn't the case, not in the layouts that you have shown. What most people forget is size constraints, embroidery has physical minimums with regard to size.
The most commonly asked for size is either a logo crest (left shirt front) and/or hat size (sometimes people want both for the same file). A typical logo crest size is usually 4" or less at it's biggest side, with the average around 3.5". Although, I have done designs as big as 5" for an LC.
Attached you'll see two screen shots of your logo sized at 4"s. One is a 1:1 view (my program is calibrated to this monitor, so 1:1 is truly 1:1 on screen, unfortunately, there might be some fluctuations with the screen shot, but it's the best that I can do) to give scale to how the design will look. The second is a blown up view to show the height of your small text which comes in at .17". That's way to small for that thin of lettering to use as normal satin stitching. At best that would have to be running stitches if you want a 100% matching of your design (even then it wouldn't look right at that size and I think running stitches as text looks awful, but that could just be me). While that size is possible, it has to be a thicker font then that, try to do that one in satin stitching and your going to have some holes. Plus at that size, you are looking at one type of block font.
You are correct with this particular design that the bridge will have to be a single color for an LC (or hat design), although gradients are possible in embroidery and would be possible in this design for a jacket back size as the type of gradient that you did is a possible stitch angle within embroidery, it's just again size gets you. I have done gradients in LCs for a couple of users on here, but again it depends on size.
Always have to think about size when it comes to embroidery. The #1 thing that I have to tell people as to why I can't convert their logo directly as is into embroidery is size, especially when it comes to text. Most assume that you can't do gradients at all in embroidery, so I typically don't have to worry about the size issue there, but text size is what gets them.
