He didn't mention if that was ALL he had on hand and wanted to brew TONIGHT.. If that was the case, then either change what you're making to fit the ingredients you have, or wait until you can get the ingredients to make what you want.. Not hard to do...
The original malt bill looks more like a brown ale than a blonde (unless it's really a brunet)... BTW, that's why I asked what he was looking to make before commenting about the ingredients... Without knowing the target, you really can't judge a recipe... IMO
I do think it's easier to make what you want when going all grain, which is what I do now... I'm getting 'essential' grains to have on hand so that I can brew almost anything at the drop of a hat. I have different L levels of caramel malts (all British Crystal malts), plus a little victory still on hand. I have a few pounds of honey malt to use, and also got some roasted barley, chocolate malt and flaked barley yesterday... Combine that with the sacks of 2 row I have (UK, Golden Promise, and Maris Otter) and I can brew a lot of different styles without issue. Of course, I still need to get some additional items to have to round out the inventory, but that will come... I do still have 4# of crystal Maris Otter (55L) to use. Used my first pound in last weeks brewing. Got another ~6 weeks to go before I open up one of those suckers (has three more weeks on the yeast, including a week of dry hopping)...
I would suggest reviewing the different styles to see what is most often used. That has helped me to figure out which grains to include in a brew... I also find that keeping the grist more basic often leads to a better brew... Just because you have 6+ different grains on hand, doesn't mean you need to use them all in a brew.
Last weeks brewing had UK 2 Row for the base, then 6oz Victory and 1# of Crystal MO... I would also suggest reading up on hops, so that you have a better idea of what they do in the brew. Especially ones that are dual purpose, or can be used for bittering, flavoring and aroma... Even ones that might not list it in their traditional descriptions, can be used for different stages.
Above all else, just brew. The more you brew, the more you'll learn what different combinations will product. Read different clone recipes, especially brews you like to drink. I would go with published ones, like from BYO or well liked books. I wouldn't trust just a google/bing search to come up with a solid recipe for you.
