Dura Ace 7401 hoods are the same as Shimano 6209 hoods, only difference is they say Shimano on the side instead of Dura Ace. Also very rare as standalone hoods, but nice complete examples show up fairly regularly on eBay for $35 or so, not a bad price for a set of good replacement hoods.
To avoid folding over older non-aero hoods, after setting up the cable and housing length, unbolt the cable from the caliper, secure the lever clamp with tape and unbolt the lever from the base. Pull the lever base out just enough to wrap the bars. After wrapping, re-bolt the lever base to the clamp and reattach the cable to the caliper. A little fiddly, especially around getting the housing back into the lever body, but does save older brake hoods.
