I make and fit many wooden worktops, I'd say go for it.
However, there are a few things to consider...
Make sure you buy from a reputable supplier, ie not cheap chinese imports.
They will need oiling on ALL sides after cutting, but before installing - I'd recommend 3 coats with particular attention to end grain.
All end grain needs to be properly sanded smooth and sealed.
ENSURE they are fitted to allow movement - an over size hole and washer is ideal.
Finally, the old addage of oiling once a day for a week, once a week for a month, once a month for a year and once a year there after is'nt far wrong.
Trust me, it may seem long winded, but it's not. It's only a rub down with an oily rag and you will have tops to be proud of
Oh, make sure you use scothbrite pad. It helps push the oil in and denibs at the same time.
Don't use wire wool, it may react with the tannins and leave purple/black specks.
Try not to cut on them - but you will. But, if you DO damage, burn, stain them, you can scrub/repair them almost invisibly.
After all, there're meant to be used.
