Alternative to 5-speed twist shifter for Shimano Nexus 5-speed IGH?

I’m going to buy a SG-C7000-5D / SG-C7050-5D and don’t want to use the twist shifter. Unfortunately there aren’t many 5-speed flat bar shifters around theses days. I’ve searched for alfine shifters, but there’s no 5-speed version, so also no corresponding shifter available..

Luckily I found the Shimano SL-5S50 for Nexus, but it’s discontinued and I can’t find it anywhere in Europe. Since the Indicator Unit (Black, Y-6WX98020) and 7-speed version (SL-7S50) are still available, the following questions came into my mind:

• Can I simply swap the Indicator Unit of SL-7S50 with a SL-5S50?
• Is there another 5-speed flat bar shifter that has the same "cable pull-distance"? Maybe even without indicator?
