I think it would be of very limited usefulness. The blue is light enough that it will be difficult to wear with light blue shirts, and a sport coat that cannot be worn with light blue shirts is not particularly useful or versatile. I think it's a summery color in a F/W weight which is another issue, since one is more likely to wear lighter colored trousers during the summer months. Birdseye is generally a suiting pattern to my eye too, but I could be wrong about that. That said, I don't think it would be too difficult to pair with patterned trousers if they were of the right shade.
Many thanks, sugarbutch and archibaldleach.
What would you suggest, then, for a reasonably versatile sport coat in a blue that's not as dark as navy?
