James : Empress Maria Feodorovna was indeed Colonel in Chief (the Russians say « Shef » = Chief) of 6 regiments, but not of a Life-Guard Lancer Regiment. The 2 Guards’ Lancer regiments had Emperor Nicholas II and Empress Alexandra Feodorovna as Chiefs.
The 6th military unit which had Empress Maria as Chief was the Guards’ Equipage (Naval Guards).
For Easter 1912 his son presented her with one of Fabergé’s famous eggs : the « Napoleonic Egg » commemorating the centenary of the Russian Victory over Napoleon. The surprise inside was a folding screen with 6 miniature paintings of men with the standards or flags from Empress Maria Feodorovna’s regiments.

H. M. The Sovereign Empress Maria Feodorovna’s Chevaliers Guards Regiment, St. Petersburg, (March 2, 1881);
H. M. The Sovereign Empress Maria Feodorovna’s Cuirassier Guards Regiment, Gatchina, (May 31, 1880);
The Guard’s Equipage, St. Petersburg, (July 22, 1892);
H. M. The Sovereign Empress Maria Feodorovna’s 2nd Pskov Leib-Dragoon Regiment, Suvalki, (May, 31, 1880);
H. M. The Sovereign Empress Maria Feodorovna’s 11th Chuguev Lancer Regiment, Dubno, (May 20, 1868);
H. M. The Sovereign Empress Maria Feodorovna’s 11th Siberian Rifle Regiment, Vladivostok, (July 22, 1907).
Empress Maria Feodorovna was patron of a large number of charitable, educational & medical institutions, most of which under the jurisdiction of His Majesty’s Own Chancery for Empress Maria’s Institutions. It’s also worth noting that the Dowager Empress remained President of the Russian Red Cross until 1917. For Easter 1915, she was presented with the « Red Cross Portraits Egg » by Nicholas II :

As for Alexandra Feodorovna’s regiments, I don’t recall having posted a list yet and have seen yours. You only need to add "Her Majesty The Sovereign Empress Guards’ Lancer Regiment" of which she was named Chief on November 14, 1894.
