I tried to forget about my and my country preferences how I can. And I will not write a lot about format of competitions, rules, qualification format, antidoping, referees, quotas because too many changes should be in many sports. It is about disciplines.
Rugby/football. 1. If men's football still will be junior it have to be removed. 2. Rugby-7 looks like a promo to rugby union and it have to be removed too. 3. Men's rugby union have to be add. 4. We have men's rugby union/women's football. 5. ???. 6. PROFIT
Archery. Delete team events. Add men’s and women’s single compound events.
Athletics. Delete 50 km walking events. Add men's and women's cross long races.
Table tennis. Delete both team events. Add men's doubles, women's doubles and mixed.
Canoeing-slalom. Add women's C1.
Canoeing-sprint. Delete men's K2 200 m. Add women's C1 200 m. Maybe change women's K1 500 m to 1000 m.
Rowing. Delete men's L4-. Add women's 4-.
Cycling-BMX. Add men's and women's BMX Park.
Cycling-Mountain bike. Add men's and women's Cross-country eliminator.
Swimming. Delete 1 breaststroke, 1 butterfly, 1 backstroke, 1 medley single events for men and the same for women. Add men's 800 m freestyle and women's 1500 m freestyle.
Gymnastics-Trampolining. Add men’s and women’s tumbling.
Cycling-Road. Add Teams time trial races for men and women.
Sailing. Delete men's Laser. Add men's Star, men's and women's Kitesurfing. May be create a new mixed skiff class instead men's and women's 470.
Equestrian. Delete 3 team events. Separate men's and women's single events. So sport still will have 6 events.
Fencing. Delete men’s and women’s team events. They are for World Combat Games. Create and add 3 mixed team events for epee, foil and sabre for Olympics.
Shooting. Delete men's 50 m rifle prone. Add men's 50 m rifle running target.
Right now nothing to change with list of disciplines for badminton, basketball, diving, hockey, golf, handball, gymnastics-artistic, gymnastics-rhythmic, modern pentathlon, water polo, volleyball, beach volleyball, triathlon, marathon-swimming, synchronized swimming, cycling-track, tennis, baseball/softball, skateboard, surf, climbing.
And some more utopic ideas
Shooting. Delete all events. Create something like omnium in track-cycling for 1 pistol, 1 rifle and 1 shotgun events both for men's and women's. So it will be 6 events in general.
Boxing/judo/wrestling/taekwondo/karate and weightlifting. I think it will be better to cut many categories for every of this sport at the Olympics. Instead of this I would prefer to add to this 6 sports some categories of 3-4 another combat sport. There are a lot of candidates like wushu, sumo, sambo, aikido, Muay Thai, kickboxing, ju-jitsu, savate, budo, kendo, kudo or even MMA. Full program of any combat sport should be at the World Combat Games. For Olympics I would stay maybe 6 events (3 for men and 3 for women) for every of this sport or something like this.
And Summer Olympics needs men’s futsal, men’s beach football and high diving.
