Oh, in that case, you must give it a go. There's nothing about the image itself at 8x10 that suggests you can't do it. Just make certain the client is rational about the final result.

Only 9 or 10?!? . Trial and error is often the best (and only) way to learn. My normal scaleľup from 8X10 to 11X14 is 50%, with a 100% increase from 11X14 to 16x20. Going straight to 16X20 that means starting with 150% more light during enlarging for basic exposure and burns (dodges can be less predictable), depending on your light source and negative. Then figure it out from there. Of course, making an 11x14 first will be extremely helpful (and less costly) in fine-tuning the direction of your print. Hope you kept printing notes from the finished 8x10.
