Newborn positioners - going straight into a cot

I know that generally there has been a lot of conversation in the press about the risks of bumpers in the cot which we are not going to have. However I was wondering about newborn positioners? We want to put baby straight into cot from birth, no blankets, swaddled and in newborn positioner to provide comfort for him or her. Just wondering if this is ok? Straight from birth? We just thought Moses basket would be a bit of a waste of money as only used for short time. Also we got a camper cot not a wooden cot so we can have baby in our room with us or in own room depending. Would love to hear thoughts. Thanks!
