From this, I don't think so. A good English pale ale malt (Maris Otter, etc) would be a good replacement. Same goes with crystal malts. Try to find English crystals. For Aromatic, I would choose whatever your LHBS has on hand. Using different malts will give you a different flavor/color/mouthfeel/etc, but even if you use the same malt from the same maltster year after year, the malt will change from crop to crop, so it may be different, but maybe not noticeably so. If you are trying to clone a recipe and are given the exact maltsters used, using a different malt may make you experience a difference if doing a side-by-side. Otherwise, it'll likely be too close to notice.
