Yeah , I think 454g honey plus hops will be dry and bitter and little body. I've just put a normal mead from mexican honey (not orange blossom ..a bit darker..from Paynes Bee Farm) and to get a mead that is off dry to medium I've used 1.7kg honey plus Lalvin 71B yeast which should take it to 14%abv if I get the staggered nutrient additions right.
Last year I did a dry mead (equivalent of 1.4kg honey in a 4.5ltr batch..actual batch was 19ltrs)...was meant to be off dry but I mistakenly used EC1118 which can go to 18% and ended up with 19 litres of 0.998 FG thin acidic mead with little body...though it may turn into something good after a couple of years aging.
If you are using a beer yeast with lower alcohol tolerance you might be able to get a lower alcohol 8-10% mead but with some residual sweetness and honey flavour left over but expect you'll need more than 454g honey...I've been using this mead batch calculator this year as a guide.

Only honey beer I've done and was successful was an attempted copy of Fullers honeydew...basically a normal pale ale but with 0.5kg organic honey for a 23ltr batch which resulted in a normal pale ale but with a hint of honey flavour....quite nice.
